Palaeochersis is an extinct genus of rhaptochelydian turtle¹ from the Los Colorados Formation of Argentina.² It is known from one species, Palaeochersis talampayensis.³

Discovery and naming

Palaeochersis talampayensis is known from three specimens: PULR 68 (holotype), a skull and postcranium. PULR 69, a right tarsus and pes, and PULR 72, a skull. The three specimens were each collected together in 1992² within the Los Colorados Formation, Argentina.³⁴

Palaeochersis talampayensis was then named and described by Rougier, de la Fuente & Arcucci (1995).³

Classification

Palaeochersis was part of the Australochelyidae, being the sister taxon to Australochelys.¹⁵
